The team will travel to San Antonio in March 2015 to compete in the national finals. Notably, this is the first time in the department history that a team representing U-M has made it to the GeoWall nationals.

The competition consists of theoretical design, report writing, and construction of a reinforced earth system (GeoWall) during the national final. The team is sponsored by the U-M student chapter of Geo Institute. The team is advised by Assistant Professor Adda Athanasopoulos-Zekkos and consists of two graduate students (Athena Gkrizi, Xunchang Fei) and two senior undergraduate students (Joel Conzelmann, Rachel Thompson).

Congratulations to the team, CEE looks forward to cheering on GeoWall in nationals.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
